As a matter of fact I was raised in a religious household, and my father trained to be a minister, though never took it up. I also attended a church school. So as a teenager I read lots of e.g. C.S. Lewis, Tillich, etc. And since then I have read a ton of philosophy of religion, including D.Z. Phillips, etc. I have swum in the "sea of faith". So it's irritating, and really rather unjustified, to have my criticisms of religious belief swept aside on the assumption that I can't really understand what the religious mean when they talk about God.
In any case, the onus is really on Sam to explain why, given how he, at least, uses "God", the problem of evil ain't really so much of a problem.
Having spent ages trying to figure out what Sam does mean, and ploughing through his allusions to Wittgenstein and "forms of life", we finally discover he never actually had any such explanation.
It's all been smoke and mirrors.
Of course, I don't think Sam's a terrible person, and I don't think he is intending deliberately to dupe us. I suspect this sort of strategy - of obfuscation and smokescreen delivered with an air of intellectual and spiritual superiority - is just a habit of thought he has rather uncritically adopted having spent too much time hanging out with a certain sort of intellectually pretentious theist.
Patronizing of me to say so, I know. But it's what I think...
